I could be wrong (and it wouldn't surprise me if I was), but for what it's worth, I was under the impression that f-bodies didn't get 243 heads, just the LS6 intake.

cam-

That would be correct iirc

It wouldn't surprise me if I was wrong either. You probably are right about that. Sometimes what I've done gets mixed up with what it was prior to mods and memories get all jumbled up!

If your doing the swap 98 will work just as well as any others.

IF your going big and going for power, you won't end up using the LS1 block in a lot of the cases anyhow.

I sure as hell didn't pass up a 98 for the swap I'm doing now where I know it came out of a running TA that got sideswiped for $1600 with everything there for the swap.

Even if you didn't use the block/engine you could sell it to recoup some costs.

Right. I would honestly be happy with 450-500 at the crank. Eventually this car will go to the boss and ill buy a new toy. So the ls block will be solid for me.

imo you dont need a custom cam esp with a mild setup
Save that for guys looking for that extra 1/2 a tenth too many customs are just off the shelf pieces anyway. Err on the smaller side rather than larger focus on good headwork/intake porting, and lots of time tuning youll be real happy

Who doesnt like a rumpity cam sure we all do but as said earlier it can be overrated. A well put together package thats mild but "right" will walk all over someone with too mcuh cam. So he will sound cool sitting at the light woopee

Looks like EPS has no extra charge for custom. Same price as catalog item.

I have noticed even going a custom cam its usually the same price or just a little more. I wasn't so much trying to get a cam that just sounds good. I just wouldn't mind if it did (yes iv actually talked to people who have complained about it funny enough). Like I said before following recommendations mid 500s lift with the right amnt of duration. Around 3500ish stall and it should be a solid street car

.55 lift is tiny for an LS1. 0.6xx is the norm with cam swaps.

I agree there are some misconceptions with custom vs shelf

Majority of cams are comp grinds and comp lobes just different name but majority are same sticks

Off self cam = proven power and designed for ls plastic style intakes with set supporting mods
Custom cam = control of powerband and all other aspects like what lobes you want etc IE if guy wants a keep stock manifolds but want to make most out of there setup custom spec would be better than a off the self cam would do
or your running stock intake and dont want to buy a FAST intake but you have the best exhuast flow you might want a reverse split cam which isn't offer off the self or if you prefer a specific cam lobes

If your getting custom cam to gain 100 hp etc then you will be disappointed

But if you have specifics wants and goals then custom spec cam would be better suited for you and it's very dependent on your setup

Price wise it's the same thru EPS your not going to lose anything with either choice it's win win call him and he will guide you

most cam company's will have feel out a form on exactly what's your setup and mods you have and then they recommend a off the self or custom spec cam based on that and usually only recommend off the self if there gains to be made vs a off shelf cam

EPS had both they don't solely do custom and I still recommend EPS custom or off the shelf

Me personally I didn't like the specs of what off shelf cams offered and I didn't want aggressive XER lobes nor I didn't want comp cam lobes I called and he gave me best options to run with and I personally didn't do it to make most power over off the shelf , but most people seem to think so like stated above

Either way custom or off the self will provide what you want

LS6 = 10.5:1 CR 60 cc chamber
LS1 = 10.1:1 CR 68 cc chamber

2001-2002 had 243 heads and ls6 intake hence increase in compression

2000 and up had better following exhuast manifolds vs the old logs but in turn had smaller cam 98-99 has larger cam but more restrictive exhuast

Some 2001-2002 f-bodies had the actual ls6 block also but majority was ls1 block I only seen one f body with full ls6 from factory Idk the numbers tho most I've seen are ls1 blocks

Oil pump was upgraded also


Here good link that goes into detail the difference thru out the years

450 flywheel hp is realistic goal

So quick question. I will be swapping my tank for the 4th gen. Whats the estimated hp range on the stocker? And preference on a new one if needed?

cam-

Stock 4th gen pump can support most NA builds. Good to around 400whp but considering age? A new pump is probably wise anyways. Walboro 255 drops right in place of the stocker.

243 head was never factory installed on an 02 or older f-body LS1, they are the LS6 head from the ZO6 Corvette

Ok yea kinda figured. Thanks for the quick reply I was thinking the same pump so that works out well
